A DNA sequence reads: TACGATCATATT. Which of the following is the correct complementary DNA strand? ATGCTAGTATAA
AUGCUAGUAUAA
CGTAGCTGCGCA
GCAUCGAGUAUA

TACGATCATATT is what you have.
ATGCTAGTATAA is what you’d get.
A matches with T, G matches with C, and the U would only come into play if you were translating out of the DNA sequence.

The complementary strand of a DNA sequence that reads TACGATCATATT is ATGCTAGTATAA.

Deoxyribonucleic acid (DNA) is made up of nucleotide subunits and functions in the storage of genetic information for living cells. There are four nucleotides that constitutes the DNA molecule namely: Adenine (A), Thymine (T), Guanine (G) and Cytosine (C).In a DNA molecule, adenine (A) base pairs Thymine (T) while Guanine (G) pairs Cytosine (C) i.e. A-T, G-C. According to this question, a DNA molecule with the following sequence was given: TACGATCATATT. The complementary sequence of this DNA strand is ATGCTAGTATAA.
